Introduction
CWD800 provides two core functions in one platform: crack depth measurement and crack width measurement. It supports efficient on-site crack inspection and helps engineers evaluate structural surface conditions with quantitative data.
Technical advantages
Dual-function design supports both crack depth and crack width testing.
Automatic first-wave search during ultrasonic acquisition improves workflow efficiency.
High-definition camera captures crack images and displays width values in real time.
Portable crack positioning ruler helps quick alignment and repeatable testing.
Professional analysis software supports data processing and report generation.
Typical applications
Surface crack inspection for concrete structures and prefabricated components.
Condition evaluation for non-metallic materials such as graphite and nylon.
Quality control, maintenance diagnostics, and acceptance inspection workflows.
